Rare
Under 5% of wildlife watchers report a Tailess Disc Oakblue sighting in Singapore on a given day, based on 71 verified sightings from GBIF citizen-science data. It is the 344th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March and May–June
In those months about 10% of wildlife watchers report a Tailess Disc Oakblue in Singapore on a given day, against under 5% in April and July–February, the lowest months.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Tailess Disc Oakblue sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Arhopala
The closest relatives of the Tailess Disc Oakblue that you can see in Singapore (genus Arhopala, Oakblues) are Dull Oak-Blue (about 10%), Aberrant Oakblue (about 10%) and Major Yellow Oakblue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Tailess Disc Oakblue is recorded against all the insects logged in Singapore (71 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
